What is the relationship between thrust and pressure for a given area?
Pressure = Thrust / Area
Thrust is the total force acting perpendicular to a surface, and pressure is the thrust acting per unit area of that surface.
Pressure = \(\frac{\text{Thrust}}{\text{Area}}\)
SI unit: 1 Pa = 1 N/m2
Check: a thrust of 100 N on an area of 2 m2 gives pressure = \(\frac{100}{2}\) = 50 Pa. Adding or subtracting area from force has no physical meaning, and Thrust = Pressure / Area is wrong because thrust = pressure × area.
Hence, Pressure = Thrust / Area.
